After youths caused a disturbance on Wednesday evening, Police were forced to close Eglinton Street in Portrush for a short time whilst the incident was dealt with.
Police attended the railway station in the seaside town following a report that a large crowd of youths had gathered in the area.
On arrival, police and Translink staff broke up the crowd of up to 70 individuals and arrested an 18-year-old man for disorderly behaviour.
Following a short closure, Eglinton Street and the train station were later reopened.
